PILE on COLUMN CONSTRUCTION.

Specification or Letters Patent.

Patented Dec. 21, 1915.

Application fil ed August 3, 1914. Serial No. 854,872.

To all whom it may concern:

Be it known that I, HENRY W. SCI-ILUE- TER, a citizen of the UnitedStates, residing at -Oceanpark, in the county of Los Angeles, State ofCalifornia, have invented a new and useful Improvement in Pile or ColumnConstruction, of which the following is a specification.

The invention relates to concrete con struction and more particularly tobuildings, piers, or the like, which are constructed of reinforcedconcrete. l

The principal object of the invention is to provide a reinforced pile orcolumn which is built .up'of a plurality of primarymem bers which may becast at any convenient point and" erected in sections, and of secondarymembers which are cast'in place between the primary members.-

The utility of the invention is'obvious to one skilled in the art towhich it pertains.

Concrete to attain its maximum strength must be carefully mixed andpoured and must beallowed to set under favorable conditions. It is oftendifiicult to provide andmaintain such conditions at the point where thework is to be erected. It isespecially difficult where the number ofpieces involved is large and the time allowed to complete the structureis small. case either a large number of. forms must be Provided or themembers must be assembled before they have time to properly set which isextremely detrimental to their strength. By employing my invention theprimary members may be fabricated at any convenient point undercontrollable conditions and over a sufficient period to insure propersetting and seasoning.- .The- Work of erection can then be done quicklyand safely.

by setting the thoroughly seasoned primary In such a members in placeand casting secondary locking members therebetween.

Other objects and advantages will be evident hereinafter.

Referring to the drawings which are for same and'forming a secondarylockin firm' y -In these drawings, the column consists of a shaft 1 anda head 2, a continuous groove '3 being formed along the inner side ofthe column having an enlarged area near its base. Longitudinalreinforcing rods 4 are vertically located in the column and are tiedtogether at suitable intervals by horizontal '4, and verticalreinforcements. l0 tied together by lacing members 11 are placed in thetwo grooves, 3 which adjoin each other and form a closed cavity.Concrete is then poured into this cavity completely filling y tying thetwo primary members together and mak ngs. homogeneous structure. Ifdesired the column may be extended as shown in dotted lines in Fig. 4,and two secondary keys employed.

The invention has an especial utility in connection with piling used forsupporting piers and the like. When used in this connection the primarymembers are driven into position and the keys are placedon top of a bodyof broken stone 12 which is first tamped down in the grooves 3.

Where additional structure is to be erected on top of the piers orcolumns the vertical reinforcements 10 are allowed to extend above thetop of the column as shown at 13 and the supporting structure is erectedthereon and tied thereto.

I claim as my invention:

1. A .column having a trough-like recess in one sid'e thereof, verticalreinforcing members embedded in said column about said trough likerecess, and horizontal tie members connecting said vertical reinforcingmembers in pairs, the horizontal tie members being closely adjacent tothe sides of the trough like recess and each tie member servingto'reinforce one side of the trough like recess.

2. A reinforced concrete-column compris ing a concrete member having alongitudinal groove in one side thereof, a series of verticalreinforcing members embedded in said Concrete around the outer edge ofthe In testimony whereof, I have hereunto set column, and a series ofhorizontal tie memmy hand at Los Angeles, California, this bers rigidlyconnecting the vertical reinforc- .Z ith day of July, 1914.
